The only thing we do know is that serotonin levels (or at least a metabolite in the cerebral spinal fluid) is low, but not in every case. Since the tricyclic ADs (TCAs - eg Elavil) increase both serotonin and norepinephrine, and are generally regarded as the best of the chemical ADs, we are led to believe that norepinephrine plays a role in depression. Low levels of norepinephrine are not generally detected in depressed individuals. All neurotransmitters are linked to one another at various levels in the CNS (central nervous system), so by affecting norepinephrine and serotonin, we seem to be alleviating the symptoms of depression the best. But I believe the mechanism(s) of action of antidepressants have not yet been determined, we are just seeing the finally results and making educated guesses at how they may work. The only way to find what AD is best for you is to have adequate trials until one works. Sorry, there are no algorithms for depression, yet. We do know that certain subtypes of depression respond to certain ADs (MAOIs in psychotic and atypical depressions) but we haven't figured out all the subtypes of depression, yet, either. - Cam W.

> michaelMichael - Many drugs claim success in dysthymic disorder. Instead of listing them here PubMed has 32 articles on drug therapy for dysthmia. PubMed can be accessed at www.mentalhealth.com and click on RESEARCH, then click on DISORDER RESEARCH and look under MOOD DISORDERS for DYSTHYMIC DISORDER, the click on DRUG THERAPY and the title of the articles will come up. To see the abstracts, just click the button beside ABSTRACTS. Then you can scroll to you heart's content. Lots of good reading and good ideas, but I haven't found anything definitive, yet. Good luck - Cam W.
